If, like me, you were excited by the VitaTV and preordered one when it was announced, let me break the news for you: growing rumors today were stating that the VitaTV is currently only compatible with the JP PSN. I can confirm this is true.
As an obvious consequence of the above, the VitaTV will not let you use your account if it is not a Japanese one. Attempting to setup the device with my US account, I was greeted by a dramatic “this service is not available in your country/region” message, and bounced back to the screen asking me to enter a user id and password.
Too bad, it had begun ok, with the device letting me choose my timezone and language, just like the Vita does, and that had contributed to raise my hopes.
Updating to he latest firmware (3.00) did not change a thing. Of course, it is possible that proxy tools such as SKFU pr0xy could somehow help tricking the account creation process, but I’ll let more adventurous people try that before me.
So, there you have it, the VitaTV is currently only available for Japanese customers with Japanese accounts. You might be able to access it from outside of Japan, provided you have a Japan PSN account, but independently of your language settings, some of the services (such as the PSN Store itself) do not get translated. It is also likely that outside of Japan, many of the music/video services will not let you use them.
In the current state, if you live outside Japan and preordered a VitaTV, I’d suggest to cancel your preorder.
